Simple Sealing Solutions to Retain Lost Heat in the Home

Old, drafty windows can be a killer this time of year - both in terms of comfort and cost. Cranking up the thermostat to combat escaping heat can often double or even triple your energy bills, plus it makes your heat and cooling systems go into overdrive which can shorten their lifespan.

While I am a huge fan of the latest and greatest energy efficient windows on the market, I understand that sometimes replacing that old glass isn’t in the budget. Keeping this in mind, I wanted to give you a few tips to help you retain some of the heat you’re losing from those old windows.

First, it’s important to remember that windows are one of the biggest sources of air leaks, which is a big deal in two of our four seasons. In the cold weather they let the heat escape, and in the warm weather they let it in, making your climate control systems work much harder than they have to. While the simple solutions I've outlined below will help you retain some comfort, window replacement will be your best bet long term if you’re tripling your energy bill during certain months of the year. So let’s get to the tips:

1. Put up curtains. Believe it or not, hanging heavy fabric drapes can help you retain up to 25% of the heat in your home. This is especially true with large glass doors that aren’t being used in the winter months. The fabric acts as a barrier and while it won’t stop the air from getting out, it will slow the leakage. Plus, they can be very helpful in the summer, especially if your house gets a lot of direct sunlight.

2. Seal up gaps. Wooden window frames get warped with age and can lead to serious air leakage. For cracks that are smaller than a quarter of an inch, a silicone caulk will work to plug up areas where air can flow through. For larger gaps and places that need to still open and close, weatherstripping is an excellent solution. It comes in foam, felt, vinyl and other materials and is both cost-effective and easy to install.

3. Add a layer. Single pane windows in homes that were built more than 50 years ago simply can’t stand up to our cold winters. If you feel air coming right through the panes and the glass rattles with the wind, beef them up with some heat shrink film. This product can be found at any home supply store and can be cut to fit just about any pane. Using heat from a hairdryer, the plastic adheres to the glass, giving you a little bit of extra protection against the cold.

4. Close up the attic. While not a window, people with an attic hatch are likely losing a ton of warm air through its frame. We all know that hot air rises, so seal up that hatch with heavy duty plastic, or build yourself an insulated box to fit over the entryway if you still need access to storage.

5. Don’t forget the doors. We don’t often open the windows in the winter, but doors are a different story. They let lots of air escape, but they can’t be sealed completely because we need to use them. I always suggest inspecting your door sweep to ensure it’s not damaged, and replace it if the bristles have come loose. A door snake or seal can also come in handy, which can be purchased at any big box store or even made at home with an old pair of tights and some rice, beans, newspaper or another filling.

Leaks Around the Chimney? Blame it on the Squirrels

I received a question from a reader that I wanted to share with you. She asked: 

Dear Bob, I've had some leaking around my chimney. I thought this didn’t seem very strange considering all the snow we’ve had, but when we went to take a look at it, we noticed lots of small holes around the flashing. What would be the cause of this? - Dot B.

Dot, this is a great question and I have received so many calls about it recently so you’re not alone. Believe it or not, the culprit of the small holes around your chimney flashing is squirrels. Flashing is often made of lead, which is a soft metal that squirrels feast on because it supposedly has a sweet taste. More practically, it also helps our rodent friends gnaw down and control their fast-growing teeth. Then, of course, there is the warmth that is escaping from your attic which makes for a pretty cozy place to spend these cold winter days.

Of course, we all know that lead is poisonous, so squirrels chomping down on your flashing is very likely going to kill them in addition to opening up your roof to potential leaks. Flashing bridges the gap between the chimney and your roof, creating a watertight barrier. If it’s damaged, water can easily get into the attic and eventually down into the home. So I’d suggest dealing with the problem right away before it becomes more costly and complicated.

One simple DIY method is to cover the flashing with the taste that squirrels hate the most - capsaicin, the active ingredient in cayenne pepper. You can mix pepper sauce or powder with water and spray it on the affected areas which will deter them in the short term. Of course, a cheap and easy solution like this also has its drawbacks, and in this case, you’ll be pulling out the ladder again every time it rains or snows. 

You can also try deterring the squirrels from your roof by cutting back the branches and trees that make it easily accessible to them. Also, if food is more readily available, they are going to follow the path of least resistance. So fill up those wildlife feeders and keep them at a distance from your house.

If the pests persist, I recommend getting a professional to cover your current flashing with heavy duty copper which is neither attractive nor penetrable. Investing in one of these simple solutions will save both your home and your furry friends from an untimely demise.

Let Your House Breathe and Say Goodbye to Dangerous Moisture

You hear me talk a lot about the importance of insulation in the home, especially at this time of year and with our recent, frigid temperatures. But even if you’re the one in every four houses I visit that actually does have the right amount of insulation, chances are that your ventilation is inadequate, which can be harming both your home and your personal health in more ways than you think.

In the winter, we crank up the thermostat, sending more heat and moisture into the living quarters of our homes. We all know that heat rises to the top, which means a lot of what we’re pumping into the house will quickly find its way through the ceiling and into the attic. Now, think about when you’re in a car and the windows fog up. What do you do? Usually, you’ll increase the airflow either by using the vents or just cracking a window. A house works much the same way, except that if you don’t have airflow in the attic, the heat and moisture just gets stuck there. If the attic is very warm, that moisture will develop into mold and mildew which can fester in your insulation and rot the wood. If the attic is cold enough, the moisture will freeze into little domes or even icicles until the temperatures rise enough for the water to thaw and then be absorbed into all the places it shouldn’t be going. Neither is a good scenario.

So what’s the best way to protect your home? Start by investing in a hygrometer which measures water vapor in the air. A comfortable humidity reading is 30-60%, but 45-55% is an ideal level to maintain. If you’re seeing higher than 60% humidity in any area of your home, you’re going to be susceptible to mold, mildew and bacteria growth.

Remember, attic ventilation allows your home to “breathe” so you want to balance your intake and exhaust to ensure that what is coming in is going out equally. The best ventilation system will include soffit vents which are installed underneath the overhang of the roof to take in the air and ridge vents which are installed at the top of the roof for the hot air to escape. For this method to work efficiently, all louvered vents must be sealed off and you have to ensure that your insulation isn’t blocking the airflow. Believe it or not, most roof manufacturers will void the warranty if a proper ventilation system is not installed. Luckily, new roofing technology enables contractors to add intake ventilation directly into the roof as opposed to using soffit vents so if you’re in the market for a new roof, be sure to ask for that option.

It’s important to note that homes have different characteristics and what works well for one may not work well for another. With the right balance of air, homeowners can optimize their roof and maintain the overall health of their home and their families, but it’s always a good idea to get advice from a professional before taking on a big remodeling project. Stay warm friends.
